Oh, well, whilst we're on that, there was once FINCL (Pronounced "Finkel" and short for F***ing Idiot No C*** Likes)
On the pilots' course ahead of me there was a lonely individual called FONC (Friend Of No C***).
For a while there one of the other boys hung around with him, out of pity I imagine, and was subsequently known as FOF (Friend Of FONC). Pretty soon FOF realised why FONC was a FONC and became NAFOFA (Not A Friend Of FONC Anymore).
